文摘
- •
Chiral nickel complexes are active in the ethylene and styrene polymerization.
- •
High catalytic activities are obtained when diethylaluminum chloride is a cocatalyst.
- •
The chiral bulky sec-phenethyl group at the ligand's aryl ring influences the activity and Mn.
- •
The chiral group has a great impact on stereoregular structure of polystyrene.
